[sane-devel] A problem with Epson GT2500

[Alex Bernier]

Hello, 

I have a problem wwhen I try to scan with the document feeder of my Epson
GT2500. 
When I do :
$ scanimage --device-name=epkowa --source Automatic --adf_mode Duplex --resolution 300 --mode Binary --speed=yes --brightness 1 --sharpness 1 --format tiff --batch=try%03d.tif

I get the message: 
scanimage: attempted to set inactive option source

(It is the same thing with Sipmplex option). 


When I try :
$ scanimage --device-name=epkowa --help

I get:
[...]
--source Flatbed|Automatic Document Feeder [inactive]



I use Debian testing : libsane-extras 1.0.19.16, sane 1.0.14-7, sane-utils
1.0.19-26; I use the "epkowa" backend packaged in iscan (version 2.19.0-4
downloaded on http://www.avasys.jp/lx-bin2/linux_e/scan/DL1.do).

My document feeder is not broken : it works under Windows, and it works also
with an old sane version (when "epkowa" was still packaged for Debian, in
"libsane-extras"). 

An other precision : all works well in flatbed mode.

Any idea ?

Regards,

Alex
